在英语越来越重要的21世纪，英语成了大学生顺利进入社会的通行证，为了帮助同学们更好地学习英语，特提供以下资料：
Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago.
They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.?
Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines.The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind. Since 1960 a new kind of tool has appeared. This is the silicon chip—a little chip of silicon crystal. It is smaller than a fingernail, but it can store more than a million“bits” of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less.
They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. They will even talk and play games with us. People will have plenty of spare time. But what will they do with it? Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now??
1. The stone chip is thought to be the most important tool because it ______.?
A. was one of the first tools?B. developed human capabilities?
C. led to the invention of machines?D. was crucial to the development of mankind
2. At the end of the passage the author seems to suggest that life in future is?______.
A. disastrous B. unpredictable?C. exciting D. colorful
解析和谜底
1. D) 这是一道细节题。按照文章第二段尾句“Some scientists say that it was the key to the success of mankind”可知“stone chip”对于人类的成长起到了很是主要的浸染，这与D正好相符。?
2. B)在文章最后一段中作者说人类在曩昔的几百万年时刻里一向使用“stone chip”，人类社会发生的转变很校而我们使用“silicon chips”才不外几年，糊口却发生了巨年夜的转变。于是作者发出了疑问：“二十年后的糊口会是什么样子的呢?”，“二百万年后的世界又会是什么样子呢?”，剖明未来的糊口无法预料，这与选项B相符。
